Hi, I think some interesting questions for children to investigate and
study could include the following:
1. How many people in your family?
2. How many hours of T.V. do you watch each week?
3. What is the farthest you have ever traveled from home?
4. How many years of education did your grandparents receive?
5. How many years of education did your parents receive?

The data for these questions can be readily found by asking a question
at home or studying their own habits for a week. This data once
collected and organized can be displayed on a stem and leaf plot,
box-plots or histograms.

The box plot in #4 and #5 would show students the max, median and min #
of years that people used to receive in education. They would then be
able to compare it to their parents, the next generation, and they could
also compare it to their own generation and see the relationship that
exists between generations and the opportunities of education.

When a student looks at the box plot or histogram in #2 or#3 they would
be able to visually compare their own answers to those of the rest of
the class.
When a student looks at the bar graph, box plot or histogram in #1, they
would have a very good idea of typical family size in their local
region.
